Pope Gelasius II

Pope Gelasius II (1064-29 January 1118), born Giovanni Caetani, was Pope from 1118 to 1119, succeeding Pope Paschal II and preceding Pope Callixtus II.

Biography
Giovanni Caetani was born in 1064 in Gaeta to the House of Caetani, and in 1088 Pope Urban II made him a cardinal. In 1118 he was elected pope, taking on the name "Gelasius". During the Investitute Controversy, Henry V of Germany set up Antipope Gregory VIII and drove Gelasius out of Rome, and Gelasius died in 1119, unable to fix the issue.
